A decorative sheet includes a design layer, a primer layer and a surface protective layer formed by cross-linking and curing an ionizing radiation curable resin composition in this order on a base material. A surface of the surface protective layer is smooth. A ten point average roughness RzJIS on a rear face of the decorative sheet and a thickness T of the base material satisfies the following equation (I); and an arithmetic average roughness Ra on the rear face and a thickness T of the base material satisfies the following equation (II):T×0.30≥RzJIS  (I)T×0.20≥Ra≥T×0.005  (II)Or an arithmetic average roughness Ra on a rear face of the decorative sheet is 1.0 to 10.0 μm. A decorated resin molded article is produced by integrating the decorative sheet with an outer surface of a resin molded article at the same time as injection molding.
